More than a dozen counselors, clergy and psychologists arrived at the local high school on Monday to help friends and neighbors cope with their grief as they remembered the victims as loyal and caring people.

Dana Rhoden “always wanted what was best for her kids,” Scioto Valley Local School District Superintendent Todd Burkitt said.

The youngest victim, Christopher Rhoden Jr., was a freshman at Piketon High School.

“He was the first one that if he thought that someone wasn’t being treated fairly or felt like someone wasn’t being treated appropriately, he would speak up about it,” Burkitt said.

The teen’s siblings also had attended the school.

No arrests have been made, and officials have not said if they have any suspects.

While they have not released any details about a motive, the Attorney General’s Office did confirm Monday that one of the victims had received a threat via Facebook. Junk, the prosecutor, did not immediately respond to multiple requests from the Associated Press for comment.

DeWine also said the state’s crime lab was looking at 18 pieces of evidence from a DNA and ballistic standpoint, and that five search warrants were executed. More than 100 tips were given to investigators, and a Cincinnati-area businessman offered a $25,000 reward for details leading to those responsible.
